Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges. It is named after Soviet scientist Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate. The technique has been variously known as "electrography", "electrophotography", "corona discharge photography" (CDP), "bioelectrography", "gas discharge visualization (GDV)", "electrophotonic imaging (EPI)", and, in Russian literature, "Kirlianography".
Reverse Polish notation (RPN), also known as reverse Łukasiewicz notation, Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to prefix or Polish notation (PN), in which operators precede their operands. The notation does not need any parentheses for as long as each operator has a fixed number of operands.
Engineering Research Associates, commonly known as ERA, was a pioneering computer firm from the 1950s. ERA became famous for their numerical computers, but as the market expanded they became better known for their drum memory systems. They were eventually purchased by Remington Rand and merged into their UNIVAC department. Many of the company founders later left to form Control Data Corporation.
UNIVAC was a line of electronic digital stored-program computers starting with the products of the Eckert–Mauchly Computer Corporation. Later the name was applied to a division of the Remington Rand company and successor organizations.
Bullet time is a visual effect or visual impression of detaching the time and space of a camera from that of its visible subject. It is a depth enhanced simulation of variable-speed action and performance found in films, broadcast advertisements, and realtime graphics within video games and other special media. It is characterized by its extreme transformation of both time, and of space. This is almost impossible with conventional slow motion, as the physical camera would have to move implausibly fast; the concept implies that only a "virtual camera", often illustrated within the confines of a computer-generated environment such as a virtual world or virtual reality, would be capable of "filming" bullet-time types of moments. Technical and historical variations of this effect have been referred to as time slicing, view morphing, temps mort and virtual cinematography.
In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. Instead of negatives and prints, reversal film is processed to produce transparencies or diapositives. Reversal film is produced in various sizes, from 35 mm to roll film to 8×10 inch sheet film.
A mechanical calculator, or calculating machine, is a mechanical device used to perform the basic operations of arithmetic automatically, or (historically) a simulation such as an analog computer or a slide rule. Most mechanical calculators were comparable in size to small desktop computers and have been rendered obsolete by the advent of the electronic calculator and the digital computer.
Max Palevsky was an American art collector, venture capitalist, philanthropist, and computer technology pioneer. He was known as a member of the Malibu Mafia – a group of wealthy American Jewish men who donated money to liberal and progressive causes and politicians.
The Eckert–Mauchly Computer Corporation (EMCC) was a computer company founded by J. Presper Eckert and John Mauchly. It was incorporated on December 22, 1947. After building the ENIAC at the University of Pennsylvania, Eckert and Mauchly formed EMCC to build new computer designs for commercial and military applications. The company was initially called the Electronic Control Company, changing its name to Eckert–Mauchly Computer Corporation when it was incorporated. In 1950, the company was sold to Remington Rand, which later merged with Sperry Corporation to become Sperry Rand, and survives today as Unisys.
Bernard S. Benson was a British inventor and author.
Mitchell Camera Corporation was an American motion picture camera manufacturing company established in Los Angeles in 1919. It was a primary supplier of newsreel and movie cameras for decades, until its closure in 1979.
The Marchant Calculating Machine Company was founded in 1911 by Rodney and Alfred Marchant in Oakland, California.
Linwood G. Dunn, A.S.C. was an American pioneer of visual special effects in motion pictures and an inventor of related technology. Dunn worked on many films and television series, including the original 1933 King Kong (1933), Citizen Kane (1941), and Star Trek (1966–69).
Color motion picture film refers both to unexposed color photographic film in a format suitable for use in a motion picture camera, and to finished motion picture film, ready for use in a projector, which bears images in color.
Honeywell, Inc. v. Sperry Rand Corp., et al., 180 U.S.P.Q. 673, was a landmark U.S. federal court case that in October 1973 invalidated the 1964 patent for the ENIAC, the world's first general-purpose electronic digital computer. The decision held, in part, the following: 1. that the ENIAC inventors had derived the subject matter of the electronic digital computer from the Atanasoff–Berry computer (ABC), prototyped in 1939 by John Atanasoff and Clifford Berry, 2. that Atanasoff should have legal recognition as the inventor of the first electronic digital computer and 3. that the invention of the electronic digital computer ought to be placed in the public domain.
Showscan is a cinematic process developed by Douglas Trumbull that uses 70mm film photographed and projected at 60 frames per second, 2.5 times the standard speed of movie film.
Wirgin was a German company which is still known for its brands Wirgin and Edixa, and for its camera types like the Edina, the Edinex or the Gewirette. It was based in the Hessian capital Wiesbaden and made a line of quite inexpensive 35mm SLRs from the 1950s to the 1970s, including the Edixa Reflex and Edixa-Mat Reflex. Wirgin was West Germany's main producer of SLRs with focal plane shutter. It also produced some of the lenses for its cameras, among them several M42 screw mount lenses.
The MADDIDA was a special-purpose digital computer used for solving systems of ordinary differential equations. It was the first computer to represent bits using voltage levels and whose entire logic was specified in Boolean algebra. Invented by Floyd Steele, MADDIDA was developed at Northrop Aircraft Corporation between 1946 and 1949 to be used as a guidance system for the Snark missile. No guidance system, however, resulted from the work on the MADDIDA, and rather it was used for aeronautical research. In 1952, the MADDIDA became the world's top-selling commercial digital computer, six units having been sold.
Donald B. Prell was an American World War II veteran, venture capitalist and futurist who created Datamation, the first magazine devoted solely to the computer hardware and software industry.
The PB 250 was a general-purpose computer introduced in 1960 by the Packard Bell Corporation.
